Using Directory Proxy Server With Referrals

You can use Directory Proxy Server in conjunction with the referral mechanism
to achieve the same result. The advantage of using Directory Proxy Server in this
regard is that the load and complexity of client applications is reduced.
Client applications are only aware of the Directory Proxy Server URL. If the distribution
logic is changed, for any reason, this change is transparent to client applications.

The following figure illustrates how the scenario described previously
can be simplified with the use of Directory Proxy Server. Client applications
always connect to the Proxy Server, which handles the referrals itself.
